Answer: 5. Tundra

Explanation:

Tundra is a biome that is located in the coldest regions of the world. This is characterized by short growing seasons and low temperatures. The plants growing in these regions are short perennials. The soil in these regions is frozen and nutrition poor. Therefore, plants growing here are simple like lichens, mosses, sedges, grasses and dwarf woody plants as the soil and weather conditions cannot support the growth of deep rooted plants and trees.

What is the action force of a bug hitting a windshield?

nalin [4]

Answer:

In the interaction between the bus and the bug, we can call the force "bus pushes bug" the action force. Then the force "bug pushes bus" is the reaction force. Since these forces are a Newton's Third Law action/reaction force pair, they are exactly the same size.

Explanation:

Newtons 3rd law

An object moves in simple harmonic motion described by the equation d equals one fifth sine 2 t where t is measured in seconds a

tensa zangetsu [6.8K]

Answer:

The maximum displacement, the frequency, and the time required for one cycle are 1/5 inch, 1/π Hz and π sec.

Explanation:

Given that,

The equation of simple harmonic motion

$d = \dfrac{1}{5}\sin 2t$ .....(I)

We need to calculate the maximum amplitude

Using equation of simple harmonic motion

$y = a \sin\omega t$

Where, a = amplitude

$\omega$ =frequency

t = time

On comparing equation (I) and general equation

The amplitude is a maximum displacement traveled by a wave.

$a = \dfrac{1}{5}$

So, the maximum displacement is

$d= \dfrac{1}{5}\ inch$

We need to calculate the frequency

$\omega=2\pi f$

$f = \dfrac{1}{\pi}\ Hz$

We need to calculate the time required for one cycle

$t =\dfrac{1}{f}$

$t =\pi\ sec$

Hence, The maximum displacement, the frequency, and the time required for one cycle are 1/5 inch, 1/π\ Hz and π\ sec.

The Earth's magnetic field is approximately 0.5 Gauss. What is the magnetic energy density of this field

ser-zykov [4K]

Answer:

The magnetic energy density is $E_B = 9.95 *10^{-4} \ J/m^3$

Explanation:

From the question we are told that

The earths magnetic field is $B = 0.5 \ Gauss$

Now

$1 \ Gauss \to 1 *10^{-4} \ T$

=> $0.5 \ Gauss \to x T$

So

$x = \frac{0.5 * 1*10^{-4}}{1}$

$x = B= 5.0 *10^{-5} \ T$

Generally the magnetic energy density is mathematically represented as

$E_B = \frac{B^2}{ 2 * \mu_o }$

Here $\mu_o$ is the permeability of free space with a constant value

$\mu_o = 4\pi * 10^{-7} N/A^2$

substituting values for equation above

$E_B = \frac{(5*10^{-5})^2}{ 2 * 4\pi * 10^{-7} }$

$E_B = 9.95 *10^{-4} \ J/m^3$
